GUSTAVE MLAMY, OF PARIS, FRANCE.

EXTRA-HlGHLY-VIBRAT Application filed December To all whom it may concern.-

Be it known that I, GUSTAVE MAMY, a citizen of the French Republic, and a resident of Paris, France, have invented an Extra- Highly-Vibrating Contact-Breaker, of which the following is a specification.

This invention relates to new and useful improvements in contac t-breakers and it p articularly contemplates a high-speed-vibrating contact-breaker applicable for use in connection with induction-coils for the ignition of stationary or automobile internal-combustion motors for the production X-rays for ivireless telegraphy, mine-blasting, and the ike.

The primary object of this invention is to provide a vibration interrupter which will produce more even and rapid vibrations than are produced by devices in use 'at the present time.

This invention is illustrated in the accom panying drawings, in which Figure 1 is a plan view of a contact-interrupter constructed in accordance with my invention. Fig. 2 is a side elevation thereof with appurtenant parts shown diagrammatically, and Fig. 3 is an end elevation of the same.

The invention in the embodiment illustrated comprises a vibrating interrupter, in which a vibrating element 4 is arranged to contact with a centrally-fulcrumed oscillating lever 9, which is insulated from said vibrating element and carries adjustable means for breaking the contact between said element and lever at a selected point in the movement of the latter. In proximity to the ends of the oscillating lever and vibrating element I employ slidably-mounted standards 1, provided with clamping-pins 2, by which said standards are adapted to rigidly secure or hold in position, as illustrated, clamping-blocks 5 and 6, between which the vibrating resilient element 4 is secured, and a bracket 13, carrying a horizontal arm or bridge-piece 12, which has insulated connection with the block 6. The bridge-piece 12 is provided with apertured depending lugs Specification of Letters Patent.

18, bet'ween which the oscillating lever 9 is supported by the pin 11. The lever 9 carries a platinum iridium contact-point 8, arranged to engage a similar contact-point 7, carried by the free end of the vibrating element 4.

other end of the lever 9, which is enlarged, as shown, to act as a counterweight to the longer end. The screw 16 is designed to momentarily engage the bridge-piece 12 and disrupt the contact formed by the vibrating element 4 in a manner to be hereinafter described.

In Fig. 2 I have shown an induction-coil interposed in the battery-circuit with the interrupter and having its core pierced by a soft-iron plug carried by the interrupterplug 17. A wire leads from the positive pole of the battery to the primary circuit of the induction-coil and from thence to the bindis carried by the right-hand stan ard 1, from which leads a return-wire to the battery.

A leaf-spring 10 is employed to roduce contact between the lever 9 and the vibrating element 4 and to movably hold said lever in contact with the said element 4. In this arrangement of the arts the current passes through the post 3 of the standard 1, throu h the blocks 6 and 5, through the vibrating eFement 4, contacts 7 and 8, lever 9, sprin 10, bridge-piece 12, in 2, standard 1, bin ing post 15, and bac to battery. The batterycircuit having thus been established, the induction-coil is energized, the core magnetized, and the vibrating element 4 drawn downward, the lever 9 moving therewith under the action of the spring 10. The lever 9 moves with the element 4 until the adjustable stop 16 engages the bridge-piece 12, thereby stopping the levers movement and in consequence thereof disru ting the contact between the lever 9 an vibrating element 4. This breaks the circuit, and the coil becomes deenergized, whereby the vibrating element 4 vibrates to its initial position by reason of its own resiliency and again makes contact A stop-screw 16 is threaded through the i ing-post hand-standard. A binding- 0st 15 with the lever 9, whereby the foregoing operatiocrli is repeated as long as current is supp Having fully described my invention, I 5 claim A vibrating interrupter having a vibrating element, a centrally fulcrumed springpressed oscillating lever adapted to normally contact with said vibrating element, said Io lever being insulated from the said vibrating element and adapted to follow its movement during a portion thereof and a stop adapted to limit the movement of said lever in one direction, substantially as described.

In testimony whereof I have hereunto set I 5 my hand in presence of two Witnesses.
